Definitions

  • the present invention relates to a front structure of a railway electric locomotive with a retractable door for the access to the automatic coupler.
  • the automatic coupling device located in the front side of modern railway locomotives must be housed inside the front structure on account of aerodynamic and aesthetic reasons.
  • All the known systems provide the presence of a front door with single or double mobile panels which is opened when the access to the automatic coupler is required.
  • the door or its mobile panels keep on being opened and protruding, even during running.
  • it is impossible to make doors which also allow both the lodging of and the access to the buffers, and alternative technical solutions to carry out the same function must be designed.
  • the presence of front doors very often breaks off the aesthetic continuity of the front structure of the locomotive and causes undesired limitations to its configuration.
  • a particular object of the present invention is to provide a new front structure of a locomotive of the type described above comprising a door suitable to be kept in a opened and a closed position, and equipped with a displacement device for guiding its movement from one position to the other using the manual action of an operator.
  • Another object of the present invention is to provide a front structure of a locomotive of the type described above in which the opening and the closing manouvres of the door can be carried out without requiring excessive manual effort and without involving dangerous situations for the operator.
  • a further object of the present invention is to provide a front structure of a locomotive of the type described above in which the displacement device is suitable to withstand mechanical and aerodynamic loads caused by train motion both with closed door as well as open door.
  • the front structure for locomotives whose characteristic consists in that it comprises a movable door pivotally connected to said structure and translatable within said structure so that it can be arranged in a closed position and in a open position angularly spaced of about 90° with respect to said closed position and retracted inside said structure.
  • a door displacement unit is provided for transmitting to the door a substantially translational motion inside the structure along the longitudinal axis of the locomotive, whereas the rotatory motion of the door is manually performed by the operator against the resistance of elastic means which tend to keep the door in the closed position.
  • the door is hingedly suspended from the fixed part of the structure and is slidingly mounted, along the edges of the front opening, to achieve its axial translational motion.
  • FIG. 1 there has been indicated at 1 an outline of the fixed front part of a railway locomotive on which an opening 1a is formed, and at 2 a movable front part, thereof hereinafter called "nose".
  • the movable front part or nose 2 has such a shape that it can be accomodated without discontinuity within opening 1a and is pivotally connected at 3, to a floating frame 4 hinged at 5 to an anchor plate 6 integral with fixed front part 1 of the locomotive.
  • An arm 7, integral with nose 2 is connected to plate 6 by elastic means 8 urging against arm 7.
  • a nose displacement unit is provided, generally indicated at 9, fixed to the body of buffers 10, which are mounted on the end sill (not shown) of the locomotive.
  • the displacement unit 9 is connected to the floating frame 4 by connecting rod means 11.
  • floating frame 4 has light metal box-shaped construction and comprises an extruded tubular cross bar 12 with square section and side-arms 13 and 14 which extend upwardly and respectively downwardly from the two ends of the cross bar 12.
  • the upper side-arms 13, which lean forward with respect to the alignment axis with the lower side-arms 14, are connected by means of pivots 5 to the respective plates 6, which are fitted in the composite material of the front of the locomotive, whereas the lower side-arms 14 are connected to plates 15 which are fixed to the sides of nose 2 by means of pivots 3.
  • From plates 15 arms 7 extend in a substantially axial direction, which are connected to the respective plates 6 by means of elastic means 8, made up in particular by air springs.
  • the displacement unit 9 comprises two crank mechanisms 9a and 9b located near the sides of the front part 1 and fixed connected to buffers 10 by means of supports 16 integral with them.
  • Crank mechanisms 9a, b are connected to each other by means of a driven shaft 17, extending crosswise with respect to the locomotive, in order to assure the synchronism of their movements.
  • Shaft 17 is oversized to such an extent as to have both high stiffness as well as reduced weight.
  • a drive shaft 18 extends parallel to driven shaft 17 and comprises a tubular central part 18a and two end parts 18b made out from a solid bar, which engage with support 16 and on which gear wheels 21 of a chain transmission 20 are keyed.
  • Chain 20 engages with a second gear wheel 22, keyed on a small actuating shaft 23.
  • From the ends of driven shaft 17 two radial plates extend which act as rotating arms 19 for drive shaft 18 with respect to the fixed part.
  • Small actuating shaft 23 is mounted on a support 24 integral with buffers 10. At the ends of tubular part 18a of drive shaft 18 flanges are provided each of them bearing protrusions 27 within which a corresponding radial tooth 28 extending from driven shaft 17 is engaged. This connection between drive shaft 18 and driven shaft 17 assures the transmission of the rotation between the two shafts and a certain clearance (in particular about 30°) between them, whose function will be explained hereinafter.
  • a chain transmission 20 and a respective small actuating shaft 23 are provided for each end of drive shaft 18 .
  • a small opening 25 is provided on both sides of the locomotive so that a drive key 26 can be inserted by the operator.
  • Such key presents a reference tooth 26a, in correspondance to a notch, not shown, formed on a matching jig 25a before the fixed small opening 25, so that key 26 can neither be inserted nor extracted unless nose 2 is wholly closed or wholly open.
  • Arms 29 extend radially and rigidly close to the ends of driven shaft 17, and connecting rod means 11 engage on such arms.
  • Each arm 29 comprises, as shown in figure 6, a pair of plates welded to driven shaft 17 and an articulated joint 30 for the respective connecting rod is provided at the end thereof.
  • Each connecting rod 11 is connected, with the other end, to lower side-arms 14 of floating frame 4 by means of a joint 31 and comprises a strut 32 with a C-shaped lenght 32a to avoid interference with drive shaft 18 during the motion of the connecting rod, and a coil-spring mechanism 33 which assures the extensibility of the strut itself. In such a way it is possible to face small assembling defects which would otherwise cause damages.
  • driven shaft 17 moves from a position situated over drive shaft 18 and illustrated full-line in figure 5 towards the position, substantially overturned, illustrated in dotted line and indicated at 17a in the same figure.
  • the angular displacement of the shaft 17 is equivalent to 190° to be at least 5° beyond the dead centers at the ends of the displacement, assuring this way the irreversibility of the motion.
  • a cam-roll mechanism is provided (see figure 5) comprising a disk 34 integral with drive shaft 18 with two notches 35 along its edge which are spaced along the circumference of 190°. Inside the notches 35 a small roll 36 is engaged which is supported by a small arm 37 extending from support 16 and elastically abuting on the edge of disk 34.
  • the slide guide is formed by a pair of slides 41 (only one shown in the figures) integral with nose 2 and spaced from one another which are slidingly engaged with the edge of opening 1a where internally protruding dowels 42 are provided which engage, in turn, with seats 43 formed on slides 41.
  • nose 2 is in a backwards position with respect to the fixed part and it is possible for the operator to introduce his hand to push the nose downwardly to overcome the reaction of air springs 8 which tend to keep nose 2 up.
  • the sizing of air springs 8 is such that they balance the weight of nose 2 with slight margin whereby the rotation is mildly hindered.
  • a locking device which comprises a pair of pins 38 integral with nose 2 extending in mutual alignment toward the inside of the nose, and a cam 39 integral with small actuating shaft 23 to which pins 38 engage at the end of the rotation of 90° of nose 2 inside front part 1 of the locomotive.
  • pins 38 abut against cam 39 which is rotated backwards.
  • the closing also occurs in two steps. From the operator point of view such closing requires only the rotation of the key, since the rotation of nose 2 is driven by air springs 8. In fact, the first part of the rotation of the key makes cam 39 rotate backwards, thus releasing the pivots 38 of nose 2. This one therefore goes upwards while rotating around joints 3 because of the action of air springs 8, until slides 41 abuts against the edge of opening 1a. Keeping the key on rotation displacement unit 9 is actuated, and as a consequence of an angular displacement of the driven shaft 17 of about 190°, connecting rod 11 is translated as well as floating frame 4 connected therewith, thereby nose 2 is pushed forward.
